(b采用绝缘栅场效应管图03.28 共源组态接法基本放大电路(1 直流分析图03.29 共源基本放大电路的直流通路将共源基本放大电路的直流通路画出，如图03.29 所示。图中 Rg1、Rg2是栅极偏置电阻，R是源极电阻，Rd是漏极负载电阻。与共射基本放大电路的Rb1、Rb2，Re和Rc分别一一对应。而且只要结型场效应管栅源PN 结是反偏工作，无栅流，那么JFET和MOSFET的直流通路和交流通路是一样的。2/10 根据图 03.29 可写出下列方程 VG=VDDRg2/(Rg1+Rg2 VGSQ=VGVS=VGIDQRIDQ=IDSS1(VGSQ/VGS2 VDSQ=VDDIDQ(Rd+R 于是可以解出 VGSQ、IDQ和VDSQ。(2 交流分析画出图
